The specific embodiment
Before describing the embodiment of the invention shown in the accompanying drawing in detail, should be noted that the contemplated upgrading of the present invention needs not be as the described upgrading fully of example, and each upgrading can be according to the increase load-carrying ability that will realize and stage carrying out.Therefore, thereby for example can be by only using some additional diagonal struts and may use some additional levels poles to upgrade to increase the load-carrying ability on a small quantity, wherein said additional levels pole and the additional diagonal struts relevant bending length that has diagonal struts, horizontal strut and leg support component now that can reduce by half effectively.
On the other hand, may need to double (double up) some or all of horizontal strut and some or all of leg support components and increase supporting capacity more.Can be introduced into or by doubling change each time and the combination that it constructs the lattice tower components of upgrading for needs bringing into use suitable design consideration and correlation computations to plan sth. ahead.
It should be understood that term first upgrading and second upgrading do not mean that the upgrading order that basic lattice pylon should be realized, and the physical unit that is described to belong to second upgrading can use before being described to belong to first parts of upgrading.Therefore, the order of upgrading depends on the increase of the supporting capacity that will be implemented and the design of lattice pylon.
